Final answer:
Pneumonia is a possible post-operative complication for a patient who has had surgery to repair a hip fracture due to the immobility during recovery.
Step-by-step explanation:
After a resident has undergone surgery to repair a fractured right hip, the individual is at risk for several post-operative complications due to the immobility associated with recovery. One of these potential complications is pneumonia, which can occur due to poor air exchange as a result of immobility. In addition to pneumonia, the patient is at risk for other complications related to immobility, such as deep vein thrombosis (DVT), resulting in a possible pulmonary embolism, as well as pressure sores and urinary tract infections. The correct answer to the student's question is c) Pneumonia.
